A Novel Multi-radio Rendezvous Algorithm for Cognitive Radio Networks

Channel Rendezvous between secondary users remains a key challenge to the development of cognitive ad-hoc networks. The decentralized and heterogeneous nature of ad-hoc CRNs makes guaranteeing rendezvous across multiple users within a short time difficult. Current research focuses on single hop networks or on multi-radio platforms to reduce the Time To Rendezvous (TTR). This work presents a Novel Multi-radio Rendezvous algorithm that leverages increasing availability of multi-radio secondary users to reduce TTR in heterogeneous and anonymous CRNs with multiple users.
